Abstract

The present invention provides a sealing ring and a sealing structure that can stably exhibit sealing performance even under a high-temperature use environment. A sealing ring (100) is installed in an annular mounting groove (210) provided on the first component (200), and is in close contact with the bottom surface (211) and the second groove of the mounting groove (210) respectively. The end face (310) of the component (300) seals the gap between the first component (200) and the second component (300), and is characterized in that it is designed to seal the ring (100) under the highest temperature environment of the use environment. The circumference of the outer circumferential surface (130) is less than the circumference of the side wall surface (212) on the outer circumferential side of the mounting groove (210).

Description

technical field [0001] The present invention relates to a sealing ring and a sealing structure for sealing a gap between two components. Background technique [0002] In inverters or inverters mounted in hybrid electric vehicles (HV), electric vehicles (EV), fuel cell vehicles (FCV), etc., a sealing ring for waterproofing is provided between the case body and the cover body. That is, the case body and the cover are sealed by attaching the seal ring to the annular mounting groove provided in one of the case body and the cover body, and making the seal ring abut against the groove bottom surface of the mounting groove and the end surface of the other member. gap between the bodies. Furthermore, many of these case bodies or lids are made of aluminum die castings. Generally, the dimensional accuracy of aluminum die castings is not very high. In this case, by forming the cross-sectional shape of the seal ring to be longer in the vertical direction than in the horizontal direct...
